The Muncie A20-A1007-HX1BS or A20A1007HX1BS is a medium-duty, 10-bolt clutch shift power take-off engineered for Allison 3000 and 4000 Series transmissions. Part of Muncie's A20 Series, it features a rotatable pump flange and a shift cover with 360-degree rotation, making installation and plumbing layout more flexible. Tapered roller bearings extend service life, while an increased output shaft diameter adds durability under load. The proven clutch pack design carries a single intermittent and continuous torque rating across its speed range, and three housing arrangements give you flexibility in mounting orientation. Extended-length PTO mounting fasteners and compatibility with the EX Drive shaft extension round out the install-friendly design. Call us at Pro Gear and Transmission to confirm the correct configuration for your application.
